The 2400 series is a series of Chicago 'L' cars built between 1976 and 1978 by Boeing-Vertol of Eddystone, Pennsylvania. 200 cars were built (numbered 2401–2600) and, as of 2014, 58 of them remain in service.

The 2400 series was the third series of five interoperable series of Chicago 'L' cars known as the High Performance Family. These cars were the first 'L' cars built since the 4000 series of 1914 to feature sliding doors rather than the folding blinker doors featured on the other cars that were in service at the time, with wider doorways allowing the cars to accommodate wheelchair-bound persons. The 2400-series cars also featured smooth steel exteriors as opposed to the corrugated exteriors of the previous series. As delivered, the cars featured a red, white, and blue color scheme on the front and rear of the cars, as well as stripes along the sides. Cars 2401–2422 were later modified to be used for work service as well as revenue passenger service and given red and white striping along their sides as well as on the front and rear of the cars. They were refurbished at the Skokie Shops in Skokie, Illinois between 1987 and 1995.

Beginning in Fall 2003, the red, white, and blue colors on the ends of the cars were removed, as were the stripes on the sides, giving the cars an unpainted steel appearance similar to the rest of the 'L' fleet (including the 2400-series cars, which were also being stripped of their stripes at this time). This was done so as to give a more unified appearance, as well as to reduce maintenance costs. The "work" cars retain the red and white striping on their ends, but the stripes on their sides have been removed.

In the 1990s, the 2400-series cars were used on the Red Line in mixed sets with unrefurbished 2600-series cars. While the 2600-series cars were being refurbished, the 2400-series cars were used temporarily on the Red Line. Currently, this series comprises part of the rolling stock for the Orange Line. Until late May 2014, these cars were also assigned to the Purple Line; for the entire 2000s and early 2010s, the Purple Line fleet consisted entirely (or nearly entirely) of these cars. The Purple Line fleet of 2400-series cars has been retired and has been replaced by 2600-series cars which were displaced from the Red Line as more 5000-series cars were assigned to that line, and since April 2014, several 5000-series cars have been assigned to the Purple Line as well. The Orange Line fleet of 2400-series cars are currently in the process of being retired as well, and are being replaced in the interim by 2600-series cars being displaced from the Blue Line, where the lost capacity on the Blue Line is made up from reassignment of 2600-series cars from the Red Line (which are newer than the existing Blue Line cars) as they are displaced by the new Bombardier-built 5000-series cars on the Red Line.
